Title:
HEAT METER AND METHOD FOR CALCULATING HEAT CONSUMPTION USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/098425
Kind Code:
A1
Abstract:
The present invention relates to a heat meter. According to the present invention, provided are a heat meter and a method for calculating heat consumption using same, the heat meter comprising: a flow meter which comprises an impeller rotating according to the flow of a working fluid used for heat transfer, and a pulse output unit for, on the basis of the rotation of the impeller, generating an electric pulse at a predetermined unit flow; a supply-side temperature sensor which measures the temperature of the working fluid entering into an object undergoing heat transfer; a return-side temperature sensor which measures the temperature of the working fluid being discharged from the object undergoing heat transfer; and a calculation unit which calculates flow by calculating the pulse generated from the pulse output unit, and which calculates heat consumption by using the supply-side working fluid temperature measured by the supply-side temperature sensor, and the return-side working fluid temperature measured by the return-side temperature sensor, wherein the pulse output unit generates a pulse by detecting the rotating direction of the impeller and increasing the flow when the impeller rotates in a direction corresponding to a forward directional flow, and decreasing the flow when the impeller rotates in a direction corresponding to a reverse directional flow.
